Thankfully it doesn't destroy the dialog after ShowModal() since for
many dialogs thats when you get the values that the user had entered,
eg. the file dialog.

They all already have it through the wxWindow base class.

That's interesting, but since the GC in lua completely changed from 50
to 51, probably not too helpful. I guess we'll have to find a way to
force 51 to be a little more aggressive.

Well, this points to luasql as being the culprit. What if you just add
the luasql files directly to your project instead of compiling it as a
separate lib?
